Hello
I want to enable password policy on Openldap 2.4.30(to all users. I see
that the ppolicy.ldif and ppolicy.schema are listed under
/usr/local/etc/openldap/schema but are not present on
/usr/local/etc/openldap/slapd.d/cn=config folder. So do I need to add
the policy.ldif to the cn=config folder ? Is there like specific
procedure to do that or can I add manually with ldapadd ? Also how do I
enable that schema to all users ? Please help.

You don't enable a schema for specific users, you just load it in server
memory.

The rest of your questions is more related to the use of dynamic
configuration in general, rather than specific ppolicy configuration.
